Remarks

Use the XPInstantFeedbackView component to work with DevExpress grid controls in instant feedback mode. The component combines the advantages and features of XPInstantFeedbackSource and XPView.

XPInstantFeedbackView ships with the following capabilities:

  • Ability to handle large data sources with lower memory usage (does not load an entire persistent object instance).
  • Ability to customize SELECT statements to exclude unused data columns.
  • Ability to include reference property data (nested properties) in the root query to avoid the 1+N problem.
  • Ability to include custom (virtual) properties calculated on the server side (similar to ServerViewProperty).

The following examples demonstrate how to work with XPInstantFeedbackView:
